The Rohde & Schwarz FSU67 is a high-performance spectrum analyzer delivering direct frequency coverage from 20 Hz to 67 GHz without external harmonic mixers. This eliminates measurement compromises inherent to external mixer architectures, providing superior accuracy, wider dynamic range, and higher reference levels across the full operating band.
The instrument delivers exceptional RF performance metrics: displayed average noise levels reach -152 dBm at 2 GHz and -148 dBm at 26 GHz (both at 1 Hz bandwidth), with third-order intercept exceeding 20 dBm (typically 25 dBm). Phase noise performance stands at -160 dBc/Hz typical at 10 MHz carrier offset. Total measurement uncertainty is held below 0.3 dB.
